A fairly secretive species, the bluethroat spends much of the time hidden in thick vegetation foraging for invertebrates such as flies, ants, beetles and spiders, which it gleans from the stems and leaves of plants, or catches by turning over leaf litter on the ground. It will occasionally catch insects on the wing, and has also been reported to feed on earthworms, shrimps, small snails and small frogs. In the winter, the bluethroat also feeds on seeds and fruits (2) (4).
Throughout the majority of its range, the bluethroat breeds between late April and July. The nest is built primarily by the female, amongst grasses and scrub on wet ground, and is a deep cup of leaves, small twigs, rootlets, grasses, plant down and moss, which is lined with hairs from animals, such as cattle or reindeer. Between 4 and 7 eggs are laid inside the nest, and are incubated for 13 days. After hatching, the young chicks remain in the nest for a further 13 to 14 days, and are fed mainly beetles, spiders and insect larvae (2) (4).
